New AP6 record
- Here are 2 new AP6s at 3004 digits:-
are prime for n=0..5
All confirmed prime with PFGW -tc
The first, having the larger 6th term, is the new record.
Numbers tested by NewPGen: k*6977#+1 for 1*10^9<k<=2*10^9
NewPGen reduced these (by sieving with all primes < 10^13) to: 3.0*10^8
Candidates checked by PFGW before AP6s found: 3.4*10^7
PRP's (AP1s) found by PFGW: 260015
Both AP6s were found by extending all the AP5s upwards.
At most one was to be expected.
Poisson seems to be in a good mood these days (cf. Ken's and David's recent posts)!
NewPGen: 71 GHz-days
PFGW: 312 GHz-days
Pascal program to find AP's: 10 GHz-mins
According to my
Ken's existing 2153-digit record had a "score" of 76.746.
This one scores 80.077, which puts it into 8th position overall.
Over to you, Ken:-)

I completed my AP4 trawl at (about) 12050 decimal digits.
Poisson expectation: 3.1 AP4 chains.
Found: 3 chains.
So I ain't complaining :-)
